In Islam, Wahi means divine revelation — the message sent by Allah to His prophets. According to Islamic scholars, there are mainly two kinds of Wahi when we talk about its role in religious guidance.

The first type is Wahi Matlu (Recited Revelation), which refers to the verses of the Holy Quran. These were revealed to Prophet Muhammad (PBUH) through the angel Jibreel (A.S) and are recited in prayers and preserved in written form. Wahi Matlu is the actual word of Allah, unchanged and memorized by millions of Muslims worldwide.

The second type is Wahi Ghair Matlu (Non-Recited Revelation). This refers to the messages from Allah that were not part of the Quran but were conveyed to the Prophet (PBUH) for guidance. These include the Hadith — sayings, actions, and approvals of the Prophet — which also serve as an essential source of Islamic teachings.

Both types of Wahi are critical in Islam. The Quran provides the divine law, while Hadith explains and supports it in practical life. For example, the Quran commands Muslims to pray, and Hadith shows the method.

Some scholars also mention other forms or methods of Wahi like inspiration to the heart, dreams, or direct speech behind a veil (as mentioned in the Quran), but these are more about how Wahi was delivered, not separate types in the legal or theological sense.

So, the correct answer is: Two — Wahi Matlu and Wahi Ghair Matlu. Understanding this is key in Islamic studies because it helps explain how divine guidance was preserved and passed down through generations. These two kinds of Wahi form the foundation of Shariah and are a frequent topic in exams and religious discussions.
